The order applies to the DC output voltage is 1V, 1.018V, 10V voltage standard solid initial verification, Use and subsequent verification check.

2 Terms

Japanese drift rate driftrate Within a period of change in output voltage divided by the number of days included in the period.

3 Overview

Standard solid-state voltage as a DC voltage standard for test/calibration of high accuracy and versatility of digital voltmeter Calibration, etc., can also be saved daily DC voltage value. Voltage standard solid core element is a Zener diode, it is divided into discrete zener diode solid-state voltage standard Type solid-state amplifiers and reference voltage standard. Generally solid state voltage standard output voltages are designed to 10V, 1.018V and its output is 1V Through the 10V reference voltage divider obtained, shown in Figure 1. Figure 1 Schematic solid state voltage standard Vz- warm padded Zener diode; N- integrated amplifier
